I am also seeing this problem with some variations in behavior depending on what I am trying to do. I see it with multiple brands and types of USB drives.
I tried different versions of the kernel. It seems to have appeared in the 3.13.0-35 kernel. I do not see it while using the 3.13.0-34 kernel, but see it in newer kernels. It is present in both the generic and low latency versions of the kernel. I have tried the Utopic kernels 3.16.0.37.29 with the same results. I have also tried the upstream kernels 4.0.3-040003, and 4.1.0-040100rc3 and still see the problem. I have multiple systems, and am only seeing this on systems with AMD processors and certain nVidia chipsets, for instance GeForce 6100 Northbridge/nForce 410 Southbridge. Please let me know if you need additional information. I will be happy to provide any information that you would find helpful. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1434764 Title: External HDD stop working Status in linux package in Ubuntu: Incomplete Bug description: [ 1026.241834] blk_update_request: I/O error, dev sdc, sector 205592175 [ 1026.241853] EXT4-fs warning (device dm-0): __ext4_read_dirblock:884: error -5 reading directory block (ino 6426347, block 0) [ 1441.263728] sd 6:0:0:0: rejecting I/O to offline device [ 1441.263737] blk_update_request: I/O error, dev sdc, sector 0 [ 1441.265369] sd 6:0:0:0: rejecting I/O to offline device [ 1441.265375] blk_update_request: I/O error, dev sdc, sector 0 [ 1441.265410] sd 6:0:0:0: rejecting I/O to offline device [ 1441.265415] Buffer I/O error on dev dm-0, logical block 13139968, lost sync page write [ 1441.265418] JBD2: Error -5 detected when updating journal superblock for dm-0-8.
